Both children are pictured hoisted high above the crowd on their father's shoulders, holding handmade signs. Seven-year-old Meryem looks across at Adin, 9, who is smiling back at her. Her father, Fatih Yildirim, is holding a sign saying "empathy." Adin's father, Rabbi Jordan Bendat-Appell, has a sign with a message about the past -- "we've seen this before never again."
